Adorno – popular music

Adorno believed that all music was standardized apart from his favorite genre of classical. I feel this was his downside as it can be seen as obviously bias. He believed that standardized music exists in order to be preconceived by the listener ensuring success for the record companies. What he theorized is the way it is pseudo-individualized, meaning its sameness is disguised with blue chords and dirty notes. The only reason I can see that he believed classical did not follow the same rules is due to its randomness and unpredictable nature. However despite this there is an argument to say that classical music has perfect cadences meaning it still follows a genre rule.
